brute4c,
I got a # 05470409 d77. The master cylinder is a 2 chamber. I reconginize the power brake booster being a Chevy. What do you mean by keeping the master cylinder the same distance from the firewall?
The guy's name is Christopher Shimp. I am not sure if he was a member or not. But if he had some questions or tech things he was doing that would definitely help.
Thanks
Dave
